Bringing the best live video experience to Cloudflare Stream with AV1 (The Cloudflare Blog)

SVT-AV1 1.3.0 (2022-10-18)

Encoder

• Port SIMD optimizations from libDav1D making the conformant path (Inv. Transform) faster
• Enabling smaller mini-GOP size configurations and tuning it for the low delay mode
• Tuning the low-latency mode in random access targeting latencies from 250ms to 1s
• Adding GOP-constrained Rate Control targeting low-latency streaming applications
• Optimize mode decision features levels for depth partitioning, RDOQ, MD stage0 pruning in-loop filtering temporal filtering and TPL adding more granularity and gaining further quality
• Preset tuning M0-M13 to smooth the spacing and utilize the quality improvements towards better tradeoffs

Build, Cleanup and Documentation

• Update preset and API documentation
• Various functional bug fixes
• Remove the use of GLOB in cmake and use file names

SVT-AV1 1.4.0 (2022-11-30)

Encoder

• Adopted the 6L / 32-picture mini-GOP configuration as default and adjusted MD feature levels accordingly yielding higher compression efficiency gains
• Update the TPL model to account for the larger mini-gop size
• Re-tune presets M0-M12 using the gained coding efficiency for improved quality vs cycles tradeoffs
• Allow duplicate commandline parameters to be parsed and take into consideration the latter to allow AWCY integration

Build, Cleanup and Documentation

• Make include and lib paths friendly to abs and rel paths
• Update preset and API documentation
• Various functional bug fixes
• Remove manual prediction structure support

Rav1e 0.6.0 (2022-11-30)

1.4.1 (2022-12-12)

Bugfixes:

• Fix CRF with maxrate bug causing bitrate to be significantly limited for CRF encodings
• Fix command line parsing forcing 1-pass in a 2-pass encoding mode when the --keyint=xs format is used
• Fix decoder segfault due to assuming aligned buffers in the inverse transform assembly
